Abstract

PURPOSE:To prevent secular deformation of a contact part due to adhesion and generate a touch as specified, by allowing the contact supporting area to touch the non-touch surface side of the contact touching part, and thereby generating supporting. CONSTITUTION:When connectors 1, 101 are put in combination with each other the contact parts 3a, 103a of contacts 3, 103 slide relatively and stride over mutually. Then the contact part 3a moves along a touch slope 103b of the contact 103 while the contact part 103a moves along the touch slope 3b' of the contact 3. The elastically deformable parts 3b, 103b incl. the contact parts 3a, 103a are displaced against the resilience along the bottom surfaces of grooves 10, 110. At this time, the load is concentrated in the contact touching parts 3c, 103c owing to existence of the slopes 3b', 103b', and deformation of these parts is eliminated. This causes the contact part 3a to get on the touching part 103c' supported fast in the contact supporting area 114 and also the contact part 103a to get on the touching part 3c' where the contact where the contact supporting area 14 is secured, and elastic compression is generated.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called two-piece connector, which is a pair of electrical connectors, and more particularly to a support means for a conductive contact held in an insulating holder in a cantilevered manner. Relates to a connector characterized by In Japanese Utility Model Publication No. 52-12141, there is provided a conductive contact having an elastically deformable portion having a raised contact portion at its tip, a contact contact portion and a fixed portion, and the fixed portion serves as an insulating holder. A two-piece connector in which the conductive contacts are held in a cantilever shape by being integrally inserted is disclosed. In this connector, when the connectors are fitted to each other, the contact parts of the conductive contacts are in sliding contact with the contact surfaces of the elastic deformable parts of the conductive contacts, and when the fitting is completed, the contact parts of the mutual contacts are completed. Is elastically pressed into contact with the contact portion. However, in the connector provided with the conductive contact as in the known connector, the contact contact portion is a very important portion where the contact portion of the mating contact elastically presses. However, it is never directly supported by the insulation carrier, i.e. it simply extends from the insulation carrier. Therefore, the contact contact portion is deformed when the conductive contact is incorporated in the insulating holder or is deformed over time due to the pressure contact force of the contact portion, and it is difficult to achieve a given contact with the contact portion. Contact reliability may not be obtained. It is an object of the present invention to overcome the drawbacks of the prior art by making a creation on the insulating holder. According to the present invention, there is provided an elastic deformable portion having a contact portion, an elongated conductive contact in which a contact contact portion and a fixed portion are sequentially located from one end to the other end, and an insulating holder.

A feature of the present invention is that, in the above-mentioned premise, the insulation holder has a conductive contact support surface area formed by a part of the insulation holder over a range substantially equal to the length of the contact portion. The conductive contact support surface region is in contact with the non-contact surface side of the contact contact portion to support the contact contact portion. According to the present invention having the above-mentioned structure, when a pair of connectors are combined, the contact portions of the pair of conductive contacts move while sliding relative to each other to get over each other.
Furthermore, it moves while sliding relatively along the contact surface of the mating conductive contact, and along with this movement, the elastic deformable portion warps and displaces toward the back side against the elastic force. Finally,
Each of the contact portions rides on the contact contact portion of the mating conductive contact and elastically press-contacts with each other to achieve electrical connection.
